Moving a bar magnet through a coil of wire induces an electromotive force (EMF) in the coil. This phenomenon is known as electromagnetic induction, according to Faraday's law. The induced current in the wire will produce a magnetic field that opposes the motion of the magnet, following Lenz's law.
What else can I help you with?
What is moved up or down repeatedly through a coil of wire an alternating current is inducted in the wire?
A magnet or magnetic field is moved up or down repeatedly through a coil of wire, inducing an alternating current in the wire through electromagnetic induction.
How can a coil wire and a magnet be used to make elctricity?
When a magnet is moved through the coil wire, it induces an electric current in the wire through electromagnetic induction. This current can be harnessed to generate electricity in devices like generators and alternators. The coil wire and magnet setup create a simple yet effective way to convert mechanical energy into electrical energy.
How does the voltage change each time you drop the magnet through the coil?
Each time you drop the magnet through the coil, it induces a change in magnetic field, which in turn creates a voltage in the coil. This voltage fluctuates as the magnet moves through the coil, causing a change in the electrical potential.
What happens when moving a magnet through a coil of wire?
When a magnet is moved through a coil of wire, it induces an electric current in the wire due to electromagnetic induction. This occurs because the changing magnetic field created by the moving magnet interacts with the electrons in the wire, causing them to move and generate an electric current. This phenomenon is the basis for generating electricity in devices such as generators and motors.
How do you produce a current with a magnet and coil of wires?
Move the magnet up and down through the centre of the coil. The quicker it is moved the higher the voltage generated. When the magnet moves towards the coil it generates current with one polarity and when withdrawn the current reverses in polarity. This is described in Fleming's left hand rule. The voltage generated can be increased by adding more turns of wires to your solenoid. All electricity from any type of power station is produced in this way.
What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.
What does copper wire and magnets have to do with Electricity?
a magnet moved through a copper coil makes electricity
What happens when a magnet is moved towards a coil?
You will generate electricity. As the wire cuts through the magnetic field.As the magnet is moved, there will be an induced electro-motive force (EMF) which can cause a current in the coil. Once the magnet stops moving, the current will go to zero.
What is moved up or down repeatedly through a coil of wire an alternating current is inducted in the wire?
A magnet or magnetic field is moved up or down repeatedly through a coil of wire, inducing an alternating current in the wire through electromagnetic induction.

Current flows within one of these when a magnet is moved past?
Conductive coil.
What would be produced if you moved a bar magnet in and out of the wire coil?
An alternating current.
How does the voltage change each time you drop the magnet through the coil?
Each time you drop the magnet through the coil, it induces a change in magnetic field, which in turn creates a voltage in the coil. This voltage fluctuates as the magnet moves through the coil, causing a change in the electrical potential.
When a magnet is moved through a coil of wire an electric current is generated in the coil because?
the moving magnet creates a changing magnetic field around the coil of wire. This changing magnetic field induces an electric current in the wire according to Faraday's law of electromagnetic induction.
What is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
